Am I going crazy?

This one was about 4-7 miniuts

This is the same test just a couple hours later I looked again

But I’m sure I see a faint line I know the bottom one doesn’t count because it was out of the time gap but the top photo was minuits after dipping it is there a vvfl or am I going crazy?🙄
